BRAKE-RTGGING- SAFETY APPLIANCE.

Specification of Letters Patent Patented Dec. '7, 1915.

Application filed May 18, 1915. Serial No. 28,864.

'1 '0 all whom it may concern:

Be it known that I, JOHN D. THOMPSON, a citizen of the United States,residing at Brinkley, in the county of Monroe and State of Arkansas,have invented certain new and useful Improvements in Brake-RiggingSafety Appliances, of which the following is a specification. I

My invention relates to a safety appliance or supporting means for usein connection with trucks of railway cars or the like, for holding upthedifferent parts of the brake rigging, in case they should drop, dueto breakage or other accidents.

An important object of the invention is to provide means of'the abovementioned character, having noparts to work loose, separate or becomederanged, whereby the appliance is always retained in an operativecondition.

A further object of the invention is to provide means of the abovementioned character, which are simple in construction, inexpensive tomanufacture, strong and durable.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame, Figure 1 is a plan view of a truck equipped with my safetyappliance, Fig. 2 is a longitudinal sectional view taken on line-22 ofFig. 1, Fig. 3 isa perspective view of the safety appliance removed,and, Fig. 4 is a detail side elevation of a brake rod supportingelement.

In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of my invention, the numeral 5 designates a railwaycar truck, as a whole, comrising'end frames 6, carrying journal boxesreceiving the ends of axles 8, which carry wheels 9, as shown. The endframes 6 are r,igidly'connected by a transverse beam or member 10,having springs 11 arranged thereon, to be engaged by an upper transversebeam or member 12. While this is the portion of the truck. Arranged uponopposite sides of the transverse body portion or beams 10 and 12 arebrake beams 13, sus pended by links or hangers 14, secured to transversebars 15, mounted upon the trans verse beam 12. At their ends, the brakeeam-s 13, carry brake shoes 16, to contact with the wheels 9. Pivotallyconnected with one brake beam 13, as shown at 17 is a lever 18, thelower end of which has pivotal. connection with a link or rod 19,pivotally connected with a lever 20. This lever" is pivotally connectedbetween its ends, as shown at 21, with the other brake beam 13, and itsupper end is pivotally connected with a bracket 22, which is rigidlyconnected with the beam 12. It is thus apparent that when the upper endof the brake lever 18 is swung forwardly, the brake beams 13 will beswung away from each other for applying the brakes, as is customary.

My safety appliance comprises inverted preferably approximately U-shapedhangers, or supporting members 23, adapted to straddle the transversebody portion or beams 10 and 12, to be supported thereby. Near its lowerend, these hangers carry lateral extensions 24, having apertures 25, for

-or the like. The rods 26 are also apertured inwardly of and near theknuckles 25' to receive cotter pins 30 or the like, the two sets ofcotter pins seiw ing to prevent longitudinal displacement-of the hangerswith relation to the rods. rods 26 carry depending supporting members31, apertured at 32 for receiving the link or rod 19, to support it inthe event that it should become disconnected from either of the levers18 or 20.

From the foregoing description it is obvious that upon the links14-breaking, the brake beams 13 will be held Within the aperturedextensions 24 and supported thereby. It is also apparent that the linkor rod 19 It is tobe understood that the form of my -invention herewithshown and described is preferred example of the same, and that variouschanges in the shape, size, and arrangement of parts may be resorted towithout departing from the spirit of the invention or the scope of thesubjoined claims.

Having thus described the invention, I claim l. A safety appliance forbrake rigging, comprising inverted approximately U- shaped hangersadapted to be arranged upon and straddle the transverse body portion ofa truck and provided near their lower ends with lateral extensions whichare apertured substantially to be taken as a for receiving the brakebeams, as described.

2. A safety appliance for brake rigging, comprising invertedapproximately U- shaped hangers adapted to be arranged upon receivingthe and straddle the transverse body portion of a truck and providednear their lower ends with laterally extending apertured extensions forreceiving the brake beams, and rods connecting the lower ends of. onehanger with the lower ends of the other hanger.

3. A safety appliance for brake rig ging, comprising invertedapproximately U- shaped hangers adapted to be arranged upon and straddlethe transversebody portion of a truck and provided near their lower endswith apertured lateral extensions for brake beams, laterally spaced rodsconnecting the lower ends of one hanger with the lower ends of the otherhangers, and apertured supporting members carried by the rods to receivea brake link therethrough.

In testimony whereof I afiix my signature in presence of two witnesses.
